Abstract
The work presents the design of a digital watermark scheme based on DCT; it has the advantages of imperceptibility and robustness achieved by grouping every watermark bit in a group and changing only one coefficient each time in turn. The simulation result shows that the performance of the proposed algorithm is better than that of other algorithms.
